Ahem, ignore that previous post please.  Today I read in the paper that
some jerks at the Scripps Institution of Oceanography in San Diego want
to put a loudspeaker in the Pacific off Big Sur and Kauai that will
broadcast a 195-decibel sound underwater every four hours for *twenty
minutes* from now until 2004!!!  This is in the March 22nd LA Times.  As
you know, whales communicate by sound and can, I think, hear pretty
well, and it is already believed that underwater noise from ships cause
whales and other marine life problems.  As you also know, whales like to
migrate along the California coast.  This crappy idea was invented by
Walter Munk of Scripps and is being funded by the Defense Department.
The goal is to see how long it takes the sound to go from its point of
origin across long distance through the ocean (the article hinted New
Zealand), as a way of measuring the ocean temperature, to give us
information about global warming.  Now perhaps this is fine and dandy,
but this idea gives me the creeps, and I hope people who know about this
sort of thing don't let this experiment proceed without having a darn
good understanding of the possible consequences.  It sounds awful to me.
